RNAi is a valuable tool in the treatment of diseases for its potency to silence disease-associated genes in tissue culture and animal models. RNAi can be induced in mammalian cells by the introduction of chemically synthesized small interfering RNAs (sirnas) or by plasmid and viral vectors that express short-hairpin RNAs (shrnas) that can be processed to sirnas by the cellular machinery. In this review, we focus on the potential therapeutic use of RNAi. Also reviewed, are the challenges involved in developing RNAi for clinical use. Key words: RNA interference; small interfering RNA; short-hairpin RNA; gene silence RNA (RNA interference, RNAi) RNA RNA(small interfering RNA, sirna); RNA (short-hairpin RNA, shrna) RNA RNA 1 RNA 1.1 RNA 2006-11-23 2006-12-25 (KSCX2-YW-R-09) (1980 ) (1927 ) * Tel: 021-54921127 E-mail: xyliu@sibs.ac.cn
